Okay, I guess I'm the equivalent of an online-anti-vaccer here, but am I the only person, that believes it's a bit suspicious, that (nearly?) all Anti-Virus softwares are cloud-based? Sure, you get an update faster, as soon as a new countermeasure of a threat is available and suspicious behavior on your computer get reported immediately. Also a good portion of the antivirus database doesn't have to be stored on your disk, but... Maybe I missed a few points, but we entered the age off +1GB/sec-R/W-SSDs and +4GB-RAM. Should be fast enough to handle a bigger DB. Is the database size really an argument? Also I imagine it takes hours-days to write a countermeasure. And maybe even days-week to identify a new threat. Isn't an everyday to every 3 days update schedule sufficient for most threats (Viruses,cryptolockers,aso..)? As soon as I boot my computer it is, "It's me, here is my AV-programs-ID-sigature and my IP-address. Don't go and sell it to anyone!"
